D-sub, or D-shaped connectors, are an important type of electrical connector often seen in computer hardware. These connectors are frequently used for both data and power, often used to interface computer components such as IDE and SATA drives, and motherboards to other components or peripherals. D-sub connectors are available in several standard sizes, the most common of which is “DE 9” and comes numbered as “747242-3”.

The 747242-3 is an industry-standard DE 9 connector that meets the IEC-60914 specification. The DE 9 connector is composed of nine pins arranged in two rows and are commonly used for low speed serial communications, such as a computer mouse, modem or keyboard. The pins are keyed to ensure that the connector is inserted correctly.

The 747242-3 is the most common type of DE 9 connector found in the computer industry. It consists of gold-plated pins and sockets. The pins are usually insulated with an insulating material to ensure that there are no shorts between the pins and the contacts it comes in contact with. The connector is typically made of a durable plastic material and the pins are often gold plated.

The 747242-3 connector is commonly used for a variety of applications, but most notably in the industry of computer technology. It is widely used in many motherboards to connect to components such as IDE and SATA drives. It is also used to connect video cables and serial ports. It is also commonly used as a data and power port on various external devices such as scanners and printers.

The working principle of a 747242-3 connector is quite simple. Once the connector is inserted into the correct port, the pins are in contact with corresponding sockets. This creates a physical and electrical connection between the two components. The current created by the electrical connection can then flow from one device to the other to allow data to be transferred.

The 747242-3 application field and working principle are quite important to understand when looking to build or maintain computer systems. This connector is a useful tool in connecting computer components, as well as peripherals, and allows for the data and power flow necessary for the components to function properly. The DE 9 connector, especially the 747242-3 variant, is a versatile and well-known component within the computer industry and can be extremely useful in ensuring that components can communicate properly even in modern, complex hardware setups.
